I just got the Silver RS 1 some hours ago.
I first got to listen to these a couple of months ago when I went to their showroom to purchase the Bronze B1 (or B2?). Then, the salesman suggested that I listen to the RS1. Wow, the difference in sound quality was obvious so I decided to hold off my purchase and think about it. Since then, I couldn't forget how thrilling the sound was. So I saved up some more for these.
I've been 'breaking it in' nonstop with every kind of music I can think of since I got home. Heavy Metal, Hard Rock, Jazz, New Age, Classical, name it, and wow, it has been delivering the goods!
